Right now there's only lessons from two books.  We should be able to generate lessons for: - JLPT - Most common kanji - A few books listed in the dictionary database

Add an option during lessons to mark individual kanji as 'learned'

Show graphs or stats on review screen how number of mastered kanji (over time?) to give user warm fuzzy feelings

Add a settings screen to the main menu.  Example settings: Fade in word-definition vs. click vs immediate, show end-of-kanji screen for a short time vs. wait for click

Right now there's no indication when the user needs to click to move to the next question.  Add that somewhere.

And test that stuff still works correctly

I think I included fixes in one or two of them, try to get them merged into the main repo instead...

Show a warning box when the user decides to review before the review date

Only consider items that haven't been done in the past 8 hours.

So that we can quit a session halfway through and still have accurate correct-percentage

Specifically, the geometry math and selection logic

And allow bonus time to be unbounded

This will require backing up the database on my phone (again)

Right now buttons look like garbage because there's no click-feedback.  Add that.
